Schering-Plough, marketer of high-profile allergy products Claritin and Clarinex, last month decided not to exercise its option agreement related to ALK-Abello's grass-pollen allergy tablet and other non-injectable allergy products, the company reported.

ALK-Abello has reacquired the exclusive worldwide. rights to these products, ending the collaboration the two companies entered in October 2002.

Given that many prescription allergy medications are either switching to OTC or are in danger of being forced OTC, introducing a prescription-only allergy remedy may not be as promising as it once was.
